MODINE, OF BACIINE, WISCONSIN, ASSIGNOR TO MODINEMANUFACTURING COMPANY, OF RACINE, WISCONSIN, A. CORPORATION OF WISCONSINI I RADIATOR Original application filed March 25, 1927, Serial No.

1930. Serial No. 450,729.

My invention relates to heat exchange apparatus and has among itsobjects the production of an apparatus of the kind described which isconvenient, compact, durable, efficient and satisfactory for usewherever found applicable.

A particular object of the invention is to provide improved radiatorsfor heating dwellings, the device being particularly designed to inducea circulation of air through the radiator to thereby heat the air anddischarge it in a heated condition into the room.

Another particular object of the invention is to provide an improvedheating unit which may be positioned in a wall or floor of a room, orthe like, and is constructed to induce a circulation of air into theroom.

The invention also has as a particular object combining heat radiatingfins with tubes through the latter of which the heating mediumcirculates and to arrange the heat radiating fins relatively to thetubes, so that circulation of air in the manner above referred to isaccomplished.

The invention has these and other objects, all of which will beexplained in detail and more readily understood when read in conjunctionwith the accompanying drawing which illustrates one embodiment which maybe employed, it being obvious that changes and modifications may beresorted to without departing from the spirit of the appended claimsforming a part hereof.

In the drawing, wherein like reference characters indicate like orcorrespondingparts:

Fig. 1 is a front elevation of a radiator embodying the invention;

Fig. 2 is a section taken on the line 2-2 of Fig. 1; and

Fig. 3 is a section taken on the line 3-3 of Fig. 1.

This application is a division of my ap-' plication, filed March 25,1927-Serial No. 178,491, which has now matured into Patent No.1,851,720, granted March 29, 1932.

In the embodiment of theinvention herein shown and described, theradiator or heat exchange device is generally identified by 178,491.Divided and this application filed my a,

the reference character 10 which includes a radiator unit generallydesignated 11. The radiator unit 11 preferably comprises a plurality ofspaced headers or tanks 12 and 13 which communicate with each otherthrough a plurality of tubes 14. In this embodiment of the invention,the tanks 12 and 13 are disposed substantially horizontal and the tubes14 are disposed substantially vertical. The ends of the tubes 14 aresecured in header plates 15 and. 16, each of which is provided withflanges 17 which are soldered in grooves 18 formed in the header tanks12 and 13.

The tubes 14 may be of any desired outline and are preferably ofelongated cross section and are also preferably formed of relativelythin. sheet metal. Heating fluid supply and return pipes 19 and,20 areprovided for connecting the tanks 12 and 13 to the hot water or otherheating system. A

casing or housing 21forms part of the radiator unit generally designated10 and provides a passage 22', through which the passage of air iscontrolled through the medium of a damper 23.

The damper 23 is secured to a rod 24 which is journalled-in opposite endwalls 25 and 26 of the casing 21. The rod 24 of the damper is providedwith a knob or handle 27 whereby the damper may be manually rotated tobring the damper into a plurality of adjusted positions.

The structure illustrated includes a plurality of sets of heat radiatingfins 28 and 29 which are soldered or otherwise secured to the tubes 14and extend transversel ..t0'

1 located will enter the casing air is directed diagonally upwardbetween the set or bank of fins 28 from which the heated air isdischarged from the radiator into the room in which the radiator 1slocated. It is manifest that the relatively' cool air existing in thelower portion of the room in which.the heat exchange device 1s 21through the spaces provided between t e plates or fins and tubescomprising the bank 29, be heated thereby during its passagetherethrough, and thence be guided by the casing 21 toward the set orbanks of fins comprising the bank 28, through which the air previouslyheated by the tubes and banks of fins 29 passes and is thence dischargedfrom the passage 22 and into the room in which the device is located,-thus providing means facilitating the circulation of the air while saidair is bein heated.

Having thus described the invention, what I claim and desire to cover byLetters Patent is:

1. Ina heat exchange device, the combination of a plurality of verticalspaced tubes,

. headers arrangedat the opposite ends of said tubes and providing meansconnecting said tubes, a casing extending from one header to the other aplurality of spaced fins in contact with said tubes arrangedtransversely of said tubes and at an angle to the vertical said finsbein arranged in sets, the fins 0% one set being disposed at an angle tothe fins of another set and providing means for heating and inducin thedirecting of air intoand out of sai casing.

2. In a heat exchange device, the combination of a plurality of tubesarranged in spaced relation to each other and banks of fins in contactwith said tubes arranged transversely of said tubes at an-angle to aplane transverse of the axis of said tubes and the fins of one bank beinarranged at an an le to the. fins of the ot er' bank and said nsprovidin means for heating air and induclng said 'eated air to beconducted in opposite directions. 3. In a heat exchange device, thecombination of a plurality of tubes arranged in spaced relation to eachother and banks of fins, the fins of one bank being arranged at an angleto a plane transverse toithe axis of said tubes and the fins of theother bank being disposed at an angle which is opposite to the angle ofthe first mentioned bank said fins providing heating means for inducingand conducting air between said fins.

4. In a heat exchange device, the combination of a plurality ofverticall arranged spaced tubes and a plurality of anks of transversefins, said fins being arranged in spaced relation and inclined to thevercontrolling the spaced relation to each other and tical and beinginclined toward each other, and a casing extending from the outermostfin of one bank to the outermost fin of the other bank said finsproviding heating means for inducing and conducting air between saidfins.

5. Heat exchange apparatus comprising a tank, a second tank arrangedabove the first-mentioned tank, a plurality of tubes extending betweensaid tanks and 'communi eating therewith, said tanks being adapted to beconnected in a heating system to sup ply heated fluid to said tubes,means forming a passage on one side of said tubes,

therewith, said tanks being adapted to be connected in a heating systemto supply heated fluid to said tubes, means forming a passage on oneside of said tubes, means extending between the tubes for inducing aflow of air into one end of the passage,

means extending between the tubes for inducing a flow of air out of theother end ofsaid passage and adjustable means for flow of air through'said passa e.v I

%. Heat exchange apparatus comprising a plurality of substantiallyvertically disposed tube sections adapted to have fluid circulatedtherethrough, fins secured-to the lower ends of said tubes and extendingfrom an end of said tube section toward the center of length of saidtube section to induce a flow of air therebetween in one direction, andfins secured to the tube sections and extendin from adjacent thecenteroftlength of saif sections toward the opposite end of saidsections to secure a flow of air therebetween in another direction, saidfins proiviiding heated means for inducing said air 8. In a heatexchange device, the combi- I nation of a plurality oftubes arranged inaplurality of banks of fins provided upon said plurality of tubes, thefins of one bank being arranged at an angle to the fins of the otherbank and being in contact with said tubes and providing means forheating air and inducing said air to be conducted in opposite directionsrelatively to said tubes, and said fins being inclined to a planetransverse to the axis of said tubes.

9. In a heat exchange device, the combination of a plurality of parallelheating fluid conducting tubes and op ositely inclined spaced meansassociate with said 1 tubes providing air passages arranged transverseof said tubes and bein inclined to a plane transverse to the axisv 0said tubes and providing an element of means for heating air andinducing all of the air circulating between said spaced means of oneportion of said tubes to be conducted in an opposite direction intocontact with another portion of said tubes.

' In witness whereof, I- hereunto subscribe my name this 25th day ofApril, A. D., 1930.
